Central Pennsylvania is everything between Greater Pittsburgh and the Philadelphia region except the Scranton/Wilkes-Barre area, including the Altoona-Johnstown area, Harrisburg, and York-Lancaster.

Northeastern Pennsylvania/Wyoming Valley is the Scranton/Wilkes-Barre area and the adjoining counties, extending into the outlying Pocono region.

Lehigh Valley is the counties of Northampton and Lehigh.

Finally, Greater Philadelphia is the Philadelphia metro area, including Chester, Berks, Bucks, Delaware, and Montgomery counties as well as the city itself.

Also, I've described parishes by precise name where such is available (generally from the parish's web page). Where it's not available, I've just referred to the generic name (i.e., "St. John"). All information has been derived from the various jurisdictions' web pages and church web pages, as well as personal knowledge and research.

Thank you! I lived in Pennsylvania for most of my life and have gotten to know the ecclesiastical geography as well as the physical. I was surprised there was no Pennsylvania page here, so I decided to be bold and get it done. I think it got them all by now... - Misha 19:24, December 30, 2005 (CST)
